perimeter beam in non-jointed floors

[blackline]

hello, when I make the slab without a beam with a perimeter beam, I get the error 'floor thickness does not meet the required requirement' Even though I increase the thickness of the slab, I get this warning again and again.

 

[mhanifiata]

You can adjust the span yourself with the reinforced concrete calculation axis edit command...

 

[mhanifiata]

If you add the entire project or the relevant floor plan, maybe we can think of more accurate solutions...

your project has reached me, but I could not open it because it is a demo version

 

[mhanifiata]

I opened your project by installing the demo version. I just edited the part about tiling without beams. The file is attached. Your maximum axis distance is 5 meters. Accordingly, I adjusted the slab thickness control to 5 meters. the problem has been fixed... but in general, you need to connect the columns to each other with fictitious beams and untie them for floor drifts, rotations etc. otherwise, these calculations cannot be made fully, especially in high-rise buildings.

hi friends, can ide solve cork flooring? I was going to write to the forum to see if there is any development on this issue. There is a development, do I not know?

yes, there is cork flooring analysis...

Isn't it necessary to check for punching for middle columns? I could not access the information with the stapling control in the reports, how can we control them?

In such systems, you need to define an additional column header for punching control. under the column menu... when you define the headings, you will see the stapling checks done in the tiling report...

the file is attached... 20 cm is enough.

yes, there is a cork flooring analysis...

For example, how do you make the cork flooring solution of a 10-storey building? How do you define fictitious beams? How do you evaluate the floor drift results? etc. etc.

 

[mhanifiata]

give the header height the same as the floor height. this is only necessary for stapling calculation in cases where beamed and cork system are combined in idestatic. For example, if your floor height is restricted by the architectural project, if there is insufficient stapling resistance, you can use a head higher than the floor for stapling. That's not what we're doing here. we just defined a header for the program to calculate stapling. if you pay attention, the other dimensions of the head are not important here... if you do not have perimeter beams, the punching calculation is already done by the program. 20 cm I chose. You can find out how low it will fall by trying it. but I do not recommend it. I use 25 cm in practice so that it does not fall below 20 cm on beamless floors. You can open the demo v6.04 project I use there...

greetings... at the moment we have a 16-storey building... its design is finished and it is in the technical drawings stage... I am giving the design of this building in order... first of all, it is necessary to create 2 building models... .model: If there are perimeter beams, the outer frame is completed with the perimeter beams, if not, the static slab edge and slab boundaries are drawn. slab placement is done. The span value in the reinforced concrete calculation axis is changed to have the slab thickness check according to the largest column span. He's making a raking account, it needs to be fixed On the inside columns, column heads are defined at floor height (or higher if necessary). this is a must for the punching calculation... this is how the system is completed and analysis is done. The tiling report is examined, if the height is sufficient and there is no problem in other element dimensions, save as is passed to the other system (2nd model). 2. model: model to be created for earthquake calculation. In this model, the columns are connected with beam elements at floor height and at the width recommended for support bands at TS500. meanwhile, the floor height had been calculated beforehand. in this way, floors are added to the system and analysis is made. this analysis is only used to determine earthquake parameters. General earthquake reports can be obtained from here. Can be combined with other system's reports. If there is no problem in this system, the drawings of both systems are combined and used. flooring reinforcements must be adjusted as bottom-top. In accordance with the principle that the beam height cannot be less than 3 times the floor height in TS500, it is necessary to arrange the lower and upper reinforcement instead of assuming that there are beams and there will be tension on the support at the top. general reports should be taken from the 1st model.

I put the mold reinforcement plan of the system. but I hope that ide authorities will definitely do new studies on cork flooring..

Thanks for what you wrote above, however, we do not solve the cork flooring in this way, the cork flooring is forced to come out, but it comes out as you mentioned. By my cork flooring, I mean those who can create a system without the need to create 2 separate models and calculate the earthquake loads, then define the fictitious beams in their own way, calculate the translations correctly, etc. The shape you mentioned is of course a possible situation, but it is so open to error and a wrong method in my opinion. If you think about it, you enter all the account openings one by one, you create a system, then you create another system and define the beams. Nobody has that much time. We talked about this issue with friends from ide 2 or 3 years ago and it was going to be developed, but there was still no development in this regard. The developments that have taken place are certainly commendable, because the idea has come to the fore from far back. Cork flooring is an issue that is missing for me and needs to be done already. Perhaps the forum title is not appropriate for a subject that I consider inadequate, but these are the expansions of U, L etc type curtains. I still spend a lot of time on drawings and fixing these curtains.

Thanks for what you wrote above, but we don't solve cork flooring in this way, it is forced cork flooring, but here it comes out as you mentioned. I mean cork flooring can be solved without the need to create 2 separate models, after creating a system and calculating earthquake loads able to define fictitious beams in their own way, calculate the translations correctly etc. etc. The shape you mention can of course be a situation but it is so open to error and in my opinion it is a wrong method.

No. We talked about this issue with friends from ide 2 or 3 years ago and it was going to be developed, but there was still no development in this regard. The developments are definitely admirable, because ide has come to the farthest point from the back. It is an issue that has been missing for me and needs to be done already. cork flooring. Maybe the forum title is not appropriate on a subject I see, but these are the expansions of U, L etc type curtains. I still spend a lot of time on drawings and correcting such curtains.

Greetings... One of the purposes of the forum is to guide the developers by bringing up such shortcomings. But what I want you to know is this: software is just a tool. They are not design geniuses. As a result, when we look at the technical books, the approach methods and acceptances are clearly seen. The software does what a calculator does, with advanced and graphical support. I've been following ide since taaa 98. and I have been using it de facto since 2003. The point we've reached is literally unbelievable. We didn't even dream of beamless slab analyzes then, which we don't like now. even in this forum, a friend had published the catalog pictures of the past. If possible, it would be great if ide officials would share those old pictures here... If you think what should happen with beamless flooring, write it here.... specify the deficiencies. I know that every subject written is noted somewhere and eventually gets a response...
